FINNEAS

"This is no humblebrag bedroom studio that turns out to have been professionally outfitted. It’s just a regular bedroom, with a bed against one wall, where Eilish sat to record her vocals, facing a desk and bookshelves and O’Connell’s modest production setup: Apple Logic Pro X, a Universal Audio Apollo 8 interface and a pair of Yamaha HS5 nearfields with an H8S subwoofer. O’Connell, who turns 22 in July, has since moved out, setting up a duplicate, slightly upgraded collection of gear at his new home, including a pair of Yamaha HS8 monitors and an Apollo X."

While Finneas' and Eilish's music became more and more minimalist over time, Finneas' studio setup was minimalist from day one. "I moved to my own house early this year, and now work from a room there, but my setup is still pretty much the same as when we did 'Ocean Eyes'. I still use Logic, and at the time I had the Roland Quad Capture interface, a set of Yamaha HS5 monitors with a Yamaha HS8S subwoofer, and an Audio-Technica AT2020 microphone, which cost $80.

He used it again for Lollapalooza 2019 in Berlin, where I saw it again. He uses it as „bass shaker“ during live on stage, for better feel.

Clearly visible in this video.
